The spleen is the body's reservoir for blood and also plays a role in red blood cell development. When a person has either malaria or sickle cell anemia the body tries to make more blood available, so the extra amount is stored in the spleen.

Where in the world are the most cases of Malaria and Sickle Cell anaemia?
Malaria is common in topical ad subtropical zones. The malaria has selected the people with sickle cell anaemia. Although person with sickle cell anemia can have malaria, the carrier, or the person with sickle cell trait is resistant to malaria.
Why does sickle cell anemia persist?
Primarily because of the same reason why any of us still persists, because even those people can reproduce. And it has been proven that people who has sickle cell anemia are immune to malaria.
What are People with Anemia resistant to?
Sickle cell anemia comes as the result of having two sickle cell chromosomes. One sickle cell chromosome makes people resistant to malaria. Unfortunately when people have two sickle cell chromosomes they can get sickle cell anemia. That makes it difficult for their blood to carry oxygen and under certain conditions makes their blood clump. The disease can be deadly. Drugs can help. It probably makes that person resistant to malaria. The sickle cell trait evolved in various places around the world where malaria is common such as Africa and Greece.

Is sickle cell anemia congenital?
Sickle-cell is inherited from parents just as physical traits. People with the disease are SS type and show the anemia. Others can carry the trait (Ss). They are able to fight off malaria. Since this type (Ss) is important in areas with many malaria cases, this is protective.
Which individuals have the greatest fitness in an area where malaria is common?
Individual homozygous for the sickle cell anemia allele
What is the symbiotic relation with malaria and people?

Can black people get chickenpox?

Who is more likely to get sickle-cell anemia?
It is more common for people of African descent to get sickle cell anemia. Sickle cell anemia is linked to survivors of falciparum malaria (P. falciparum), it is believed that the hemoglobin cells take on the sickle shape to give the mammal an increased survival rate.
